Photo, signature and thumb resizer
Enter the width, height and maximum file size from your form notification. The tool crops and scales your image to those pixels, then finds the best JPEG quality that stays under your KB limit.
Live Image KB Resizer
One slider. Real-time JPEG compression. No repeated convert clicks.
The slider changes the target and automatically regenerates the preview. Only JPEG quality is adjusted; original pixel dimensions are preserved. Actual file size depends on image content, so an exact KB match cannot always be guaranteed.
How to use it
- Choose a starting preset or type the width, height and size limit from your notification.
- Select the photo, signature or thumb image.
- Press Resize and download the result. Check the file size shown below it.
Questions
How do I reduce a photo to 50 KB?
Set the maximum size to 50, enter the pixel width and height your form asks for, select the photo and press Resize. The tool lowers JPEG quality step by step until the file is under 50 KB.
Why is my result smaller than the minimum size?
Plain images such as a signature on white paper compress very well. Most forms only enforce the maximum, but if yours needs a minimum too, use a larger source photo with more detail.
